Its also the wider application of the workers, farmers and people in daily life have a wide range of use, and with the enhancement of environmental awareness among the people, the demand for water soluble film will also continue to grow. In this paper, 400 water-soluble film-forming system of research methods, the systems main principle is: first of raw materials under certain conditions, into water-soluble glue, and then glue to flow to the inquiry with stainless steel mirror ( Hereinafter referred to strip), the scraper will Smear glue evenly, with the strip into the rotation, bake film drying, peeling into the final finished film. Hung Road to the heat source in the system to the layout at the top of the heat and bake for sending me the built-in infrared Electric Road tube, the temperature is controllable. Scraper fixed in the upper strip, it can within a certain range from top to bottom mobilization, t
